In February 2012, Selena and Justin played house for the day when they took his younger siblings to the beach for some play time.

The couple kept it super casual for a lunch date in California back in April and walked hand-in-hand to their car afterwards.

In one of their greatest PDA moments to date, Justin and Selena smooched for the world to see while on the kiss cam at a Laker's game in April.

Later that month, Selena paid a visit to her man on the set of his music video for Boyfriend... and clearly, she was marking her territory!

The couple hit the Teen Choice Awards together once again in July 2012.

After that, Justin's schedule began to get crazy as he started rehearsals for his Believe tour, which began in September. It was the couples' crazy scheduling that ultimately led to their demise -- but they've made it work before, right?! I'm not ruling this one completely over just yet!!
